Reliable PumpsCommercial has been the dump body indus-tries pump/valve combination of choice forover 30 years. They're built on our heavy-dutyP30 and P50 pump frames.

Commercial's pumps feature one-piecedrive shafts and gears made of hardened,alloy steel and supported on heavy-duty rollerbearings. Pressure balanced thrust plates pro-vide an effective seal for continuous high effi-ciency and add to the outstanding service lifeof the pump.

Relief Valve ProtectionA patented internal relief valve protects boththe pump and the cylinder circuit. With the 3-position valve in the raise position, the reliefvalve acts as a system relief to protect againstoverloading. In the hold position, it acts as aport relief protecting the cylinder from shockloads commonly encountered during roading.

In three-line hookup, oil passing over therelief valve is vented to tank. This allows forcontinuous or intermittent operation. A 2-linehookup is used for intermittent operation only.

Commercial's pump/valves are rated forpressures to 2500 psi and are available in 9.5gpm to 62 gpm (at 1800 rpm) models. Twindrive shafts permit them to be driven in eitherdirection. The valve spools can be operatedwith a lever/cable or an air shift. Relief valvesare factory set at 2000 psi.

Performance DataMaximum speed is 2400 rpm. Operating pres-sures above 2000 psi are subject to theapproval of our product support group.Performance data are the results of a series oftests of production units and are not necessar-ily representative of any one unit. Oil reservoirtemperature was 120° F, viscosity of 150SUSat 100° F. Requests for more specific informa-tion should be directed to our component salesrepresentatives.

By the Shape and Size of the Port End Cover1. Look at the Unit from the Port End, see which example it matches the closest. Include the Shape, Size, and most importantly the Bolt Pattern.2. Measure the overall width of the Unit, then match the width to the chart beside the Port End you chose in step #1. 3. If there is not a “See Also” block on the chart you used, then you’ve identified the Unit. Otherwise move to step #4.4. A Numbered Note marker will direct you to the next step or steps.

Identifying Commercial Gear WidthCompared to Pump or Motor Housing Width1. Measure the gear housing width (See Illustration).

2. Then match the housing width to the series of pump/motor you are using.

3. Check the chart for the nearest measurement (rounding up) to give you the proper gear width.

Series P20

P20General InformationCommercial’s P20 gear pumps and motors are anideal power for the truck industry. With 1/2”gears, it measures only 6” from mounting flangeto the port end cover and weighs only 25 lbs.

The P20 can produce flows up to 2.96 cir @300 psi; output to 3.94 cir up to 2500 psi.Maximum speed is 2400 rpm. Motors and pumpscan be bi-rotational.

A variety of drive shafts and mounting stylesare offered to meet your needs. Standard featuresinclude rigid, one-piece drive shaft and gears andpressure balanced thrust plates which assure topefficiency.

Performance DataPerformance data shown are the average resultsbased on a series of laboratory tests of produc-tion units and are not necessarily representativeof any one unit. Tests were run with the oil reser-voir temperature at 120°F. Requests for more spe-cific data should be directed to our sales repre-sentatives.

Performance data for pumps and motors havingother gear widths can be approximated by multi-plying values in tables below by actual gearwidth.

How To Specify and CodeThis catalog contains codes for our most popular models. Complete codes for all con-figurations are readily available upon request.

Single UnitsFull assembly codes for single units combine shaft end cover, port end cover, gearhousing and drive shaft codes. They are preceded by the letter P or M for pump or motor— and by 20 to designate the series and model. An example of an assembly code follows:

Multiple UnitsCoding is the same as single units except that codes for added components must beincluded. Each gear unit added also requires code for a bearing carrier, the additionalgear housing and connecting shaft. An example of an assembly code for a two-sectionSeries 20 pump follows:

VariationsSeries 20 units are available with gear sections ranging from 1/2” to 2” in 1/4” increments which provide displacements from .985 to 3.94 cu.in. per revolution. Two or more gear sections can be assembled on one drive shaft to provide larger flows, supply other circuits or makesmoother, more powerful motors.

When specifying multiple units you must consider the drive shaft’s strength. This is called a PL factor in which P = operating pressure and L= sum of gear widths. The recommended PL factors for various Series 20 shafts are shown with the shaft codes and are offered as a guideto shaft selection. A PL of 8000 means a maximum of 4” of gear can be operated at 2000 psi (2000 psi X 4” = 8000) without overloading theshaft. The gear widths can be divided many ways, eg. (2”-1”-1”, 1”-1”-1”-1”, 1-1/2”-1-1/2”-1/2”) to provide the output you need for several cir-cuits. This pump needs a drive shaft with a PL factor of 4500 or more to operate successfully.

Variations25 X units are available with gear sections ranging from 1/2” to 2-1/2” in 1/4” increments which provide displacements from 1.275 to 6.375 cu.in. per revolution. Two or more gear sections can be assembled on one drive shaft to provide larger flows, supply other circuits or makesmoother, more powerful motors.

When specifying multiple units you must consider the drive shaft’s strength. This is called a PL factor in which P = operating pressure and L =sum of gear widths. The recommended PL factors for various 25X shafts are shown with the shaft codes and are offered as a guide to shaftselection. A PL of 8000 means a maximum of 4” of gear can be operated at 2000 psi (2000 psi X 4” = 8000) without overloading the shaft. Thegear widths can be divided many ways, eg. (2”-1”-1”, 1”-1”-1”-1”, 1-1/2”-1-1/2”-1/2”) to provide the output you need for several circuits.

Note:Commercial Model 25X tandem pumps and motors can befurnished with either the Type I or Type II shaft. The TypeII shaft is used with a thrust bearing and a needle bearingin place of the tapered roller bearing used in the Type I, inorder to provide for the 6 bolt — 25/8” dia. pilot shaft endcover. Subassemblies are not interchangeable.

Series P30

ReliabilitySeries 30 pumps and motors are cast from hi-ten-sile gray iron and offer a wide variety of driveshafts designed for high torque input/output.Unique pressure balanced thrust plates con-tribute to operating efficiencies of over 90%.

These units are designed for continuousoperation in heavy-duty implement circuits.They’re equally at home on lift trucks, auto wreck-ers and small dump body applications.

Call our Component sales team for quickapplication assistance and pump specifications.




Single UnitsFull assembly codes for single units combine shaft end cover, port end cover, gear hous-ing and drive shaft codes. They are preceded by the letter P or M for pump or motor —and by 30 to designate the series and model. An example of an assembly code follows:

When specifying multiple units you must consider the drive shaft’s strength. This is called a PL factor in which P = operating pressure and L =sum of gear widths. The recommended PL factors for various Series 30 shafts are shown with the shaft codes and are offered as a guide toshaft selection. A PL of 8000 means a maximum of 4” of gear can be operated at 2000 psi (2000 psi X 4” = 8000) without overloading the shaft.The gear widths can be divided many ways, eg. (2”-1”-1”, 1”-1”-1”-1”, 1-1/2”-1-1/2”-1/2”) to provide the output you need for several circuits.

ReliabilityCommercial’s pumps and motors have alwaysbeen the most reliable, most efficient in the world.They’re cast from high tensile iron for strength,machined precisely for efficiency, and carefullyassembled and tested to assure long service life.

Call our Component sales team for quick applica-tion assistance and pump specifications.



How To Specify and CodeThis catalog contains codes for our most popular models. Complete codes forall configurations are readily available upon request.

Single UnitsFull assembly codes for single units combine shaft end cover, port end cover, gear hous-ing and drive shaft codes. They are preceded by the letter P or M for pump or motor —and by 37X to designate the series and model. An example of an assembly code follows:

M37X SINGLE MOTOR

Multiple UnitsCoding is the same as single units except that codes for added components must beincluded. Each gear unit added also requires code for a bearing carrier, the additionalgear housing and connecting shaft. An example of an assembly code for a two-sectionSeries 37X pump follows:

Variations37X units are available with gear sections ranging from 1” to 2-1/2” in 1/4” increments. Two or more gear sections can be assembled on onedrive shaft to provide larger flows, supply other circuits or make smoother, more powerful motors.

When specifying multiple units you must consider the drive shaft’s strength. This is called a PL factor in which P = operating pressure and L =sum of gear widths. The recommended PL factors for various 37X shafts are shown with the shaft codes and are offered as a guide to shaftselection. A PL of 10000 means a maximum of 5” of gear can be operated at 2000 psi (2000 psi X 5” = 10000) without overloading the shaft.The gear widths can be divided many ways, eg. (2”-2”-1”, 1”-1”-1”-1”-1’, 1-1/2”-1-1/2”-2”) to provide the output you need for several circuits.

Series 330 350 365

General InformationModel 330, 350 and 365 pumps andmotors are external spur gear, fixeddisplacement units designed for con-tinuous operation at pressures up to3500 psi. They combine a practicalhigh pressure capability with theeconomy and durability of gearequipment.

High EfficiencyAdvances in thrust plate designs andseal material contribute to pump volu-metric efficiency as high as 95% oftheoretical, even with fluid viscosity aslow as 50 SUS. Longer gear journalspresent a large effective area to thesleeve bearings and provide excel-lent load distribution. Internal pas-sages supply a constant flow of lubri-cation from the pump’s inlet to allbearing surfaces. This ensures a filmof clean, cool oil on all moving partsat all times. These features greatlyextend service life.

Heavy-duty ConstructionHousings are made from cast iron fordurability and strength. Units areavailable in single and multipleassemblies.

The drive gears and shafts aremachined from a one-piece forging toprovide maximum strength. Gearteeth and journals are carburized andground to a precision finish.

Cast-bronze thrust plates are pres-sure loaded and are designed to pro-vide minimum clearance at the endsof the gears for outstanding efficien-cy.

MountingsStandard SAE B 2- and 4- bolt (ANSI101-2, 101-4) and SAE C 2- and 4-(ANSI 127-2, 127-4) flange mountingsare available. Shaft end covers canhave a single or twin shaft seal. Atapped drain hole is provided whentwin seals are specified.

RotationPumps can be assembled for eitherCCW or CW rotation. Motors are bi-directional.

DrivesDirect drives are recommended.Radial loads are permissible with anoptional outboard bearing but aresubject to approval by Commercial.Contact our sales representatives fordetails.

Optional AssembliesFor those applications where it is nec-essary to provide a braking effect tothe drive unit, we offer built-incrossover relief protection. Thesemotors save plumbing and simplifyinstallations.

Performance DataPerformance data shown are the average results based on aseries of laboratory tests of production units and are not nec-essarily representative of any one unit. Tests were run with theoil reservoir temperature at 120°F. Requests for more specificdata should be directed to our sales representatives.

Performance data for pumps and motors having other gearwidths can be approximated by multiplying values in tablesbelow by actual gear width.
